Is Exness A-Book or B-Book?
How Exness executes orders, and what A-book and B-book mean for South African traders.
Open Exness Account →Exness operates a hybrid execution model: it acts as a market maker and also hedges flow with liquidity providers, so individual orders may be internalised (B-book) or passed through (A-book). For traders, the practical question is execution quality — Exness publishes fast execution speeds and a stop-out and slippage policy you can check before trading.
A-book vs B-book — and where Exness fits
- A-book: the broker passes your order to liquidity providers and earns from spread/commission.
- B-book: the broker takes the other side of your trade internally (a market maker model).
- Many brokers, including large ones, use a hybrid of both depending on the client and instrument.
- Exness is a market maker that also routes flow to liquidity providers — a hybrid model.
- What matters most in practice is execution quality: speed, slippage and requotes.

Frequently asked questions
Is Exness a market maker?
Exness is a hybrid broker: it acts as a market maker and also routes order flow to external liquidity providers, depending on the client and instrument.
What type of broker is Exness?
Exness is a hybrid, multi-regulated broker. It combines market-making with routing to external liquidity providers, offering fast market execution on MT4 and MT5 across forex, metals, crypto, energies, stocks and indices.
Is Exness a B-book broker?
Not purely. Exness internalises some flow (B-book) and hedges other flow with liquidity providers (A-book) — a hybrid model — rather than being a pure B-book market maker.
How do I know if a broker is A-book or B-book?
Brokers rarely state it outright. Judge it by execution quality instead — speed, slippage behaviour and whether you get requotes — and read the order-execution policy. Many large brokers, Exness included, run a hybrid of both.
Is A-book or B-book better for me?
Neither is automatically better for a trader; day-to-day execution quality matters more than the label. Check Exness's execution speed, slippage rule and requote policy, which apply regardless of routing.
Is Exness regulated?
Yes — Exness is a globally regulated broker holding multiple licenses from respected regulators. Always trade with the broker as it operates in your own region.
